FIREPLACE. i

Application filed July 24, .1922. Serial No. 576,955.

To all whom it may concern Be it known that I, /VALTER MORK, a citizen of the United States, residing at Berkeley, in the county of Alameda and State of California, have invented certain new and useful Improvements in Fireplaces, of which the following is a specification.

My invention is an improved fire place.

The object of my invention is to provide a simple, inexpensive and efficient fire place, which may be readily installed and operated.

Another object of my invention is to provide a fire place which is very light in weight and consequently does not require the usual heavy foundation.

Referring to the drawings which form a part of this application.

Figure 1 is a front view of my heater.

Figure 2 is a side view of the same with the heater removed.

Figure 3 is a side/view partly in section of one of the heating units.

Figure 4 is a sectional view taken on the line 4-4 of Figure 3.

Figure 5 is a bottom plan view of the heating unit.

Figure 6 is a top plan View of the heating unit.

Figure 7 is a sectional view taken on the line 77 of Figure 4.

Figure 8 is a sectional view taken on the line 88 of Figure 4.

Figure 9 is a sectional view taken on the line 99 of Figure 4.

Figure 10 is a fragmentary rear view of the fire placewall construction.

Referring more particularly to the drawings the numeral 1 indicates a fire place which is preferably formed of a plurality of sheet metal sections 2. 7

Each of the sections has inturned flanges 3 which are bolted together to form the complete structure. A pair of openings 4 in the sides of the fire place 5, lead into the space back of the front walls of the fire p ace.

At either side of the fire place 5 and back of the walls is positioned a heater 6 extending upwardly and positioned in suitable openings 5" in the shelf 5*, which comprises an outer protective casing 7 and a burner 8 under the heating unit 9. A fresh air heating chamber 7 is formed between the casing 7 and unit 9. The heating unit 9 comprises a central burner chamber 10 which extends longitudinally of the unit, and the rear wall. of which is open as at 11 giving access to an outer U, shaped chamber 12. The side walls of the chamber 12 are perfo rated-as at 13 to give access to an outlet chamber 14, which is positioned at one side of the heating unit 9. Bleed holes 15 at the top of the chamber 14 lead into the chamber 12, to assist in the circulation of the heated air. .An outlet pipe 16 extends from the top of the chamber 14 to the flue 17. An air heating passage 18 is formed by the space between the burner chamber 10 and the chamber 12, and is open at the top and bottom to allow free circulation of the fresh air.

A control valve 20 is positioned in the gas line in the recess 5, to regulate the flame of the burner 8.

Having described my invention, I claim:

1. In a fire place structure, a front wall having a rectangular o ening centrally located near the bottom tiereof, said opening adapted to receive a fire place grate, vertical end walls, a top member supported by said wallsand constituting the ledge of the,

fire place, the top member having openings therein near its ends, a gas heater unit built into said fire place within said walls and at each side of the opening in the front wall, said units being connected with the top member so as to discharge heated air through said top member, the walls of said fire place being constructed to provide open ings near the bottom of the fire place 1 through which air may be drawn by the heater units, combustion chambers in each of said units, and means for connecting both ofsaid combustion chambers with asingle outlet pipe.

2. In a fire place structure, vertical front and end walls, a top member, a base member, said walls and said member forming an inclosure for a fire place, a heater unit located near one end of said enclosure, said heater unlt lncludlng a central heating v chamber, a second chamber With Which said heating chamber communicates, said second chamber having side Walls spaced from the Walls of said heatingchamber to form an air passage, an outlet member connected With said second chamber, an outlet pipe leading from said outlet chamber, and a casing surrounding said heater unit connected to the top member of said fire place structure so that-the heater member may discharge warm air through said top member.

In testimony whereof I afiix my signature.
